11. A computer-implemented method for facilitating access to a plurality of composite services by a plurality of users having associated client machines, each of the users being associated with one of a plurality of independent enterprises, the method comprising: providing access to a network having a directory associated therewith which maps an identity for each of the users to a policy framework, the policy framework defining access information relating to a plurality of services associated with the network, one or more of the plurality of services communicating with the network via a public network, the network also having a first composite service associated therewith, operation of a first subset of the services having been integrated to enable the first composite service, integrating operation of the first subset of services including mediating policy differences between or among the first subset of services with reference to the policy framework, the first subset of services being associated with and controlled by a first plurality of independent service providers, the network also having a second composite service associated therewith, operation of a second subset of the services having been integrated to enable the second composite service, integrating operation of the second subset of services including mediating policy differences between or among the second subset of services with reference to the policy framework, the second subset of services being associated with and controlled by a second plurality of independent service providers, the second subset of services at least partially overlapping with the first subset of services; and providing an interface to one or more of the plurality of users, the interface allowing the one or more users to select one or both of the first composite service or the second composite service; enabling the client machines to connect with the network and selectively interact with the services associated with the first and second composite services in accordance with the directory and the policy framework, thereby enabling each of the users to access one or both of the first or second composite services as an integrated solution in which each of the composite services facilitates dissemination of messages between or among the corresponding subset of services.

12. The method of claim 11 wherein the policy framework specifies any of access, authentication, and encryption policies for each of the services.

13. The method of claim 11 wherein each user identity includes any of the enterprise associated with the user, a role within the enterprise associated with the user, and an identifier of the client machine associated with the user.

14. The method of claim 11 wherein enabling the client machines to connect with the network comprises using any of HTTP, HTTPS, FTP, Secure FTP, EDI, INT, AS2, SMTP, and SOAP.

15. The method of claim 11 wherein enabling the client machines to connect with the network comprises enabling connection directly via a public wide area network.

16. The method of claim 11 wherein enabling the client machines to connect with the network comprises enabling connection via an enterprise network associated with the enterprise associated with the users corresponding to the client machines.

17. The method of claim 11 wherein the first composite service comprises an eCommerce solution and the first subset of services comprises an online storefront service provided by a first service provider, a financial management service provided by a second service provider, and an online payment service provided by a third service provider.

18. The method of claim 11 wherein the first composite service comprises a customer relationship management (CRM) solution and the first subset of services comprises an online storefront service provided by a first service provider, a financial management service provided by a second service provider, a CRM service provided by a third service provider, and an expense management service provided by a fourth service provider.
